How to save an image as a variable?

问题

Now, I have a python game that has sprites, and it obtains the images from files in its directory. I want to make it such that I do not even need the files. Somehow, to pre-store the image in a variable so that i can call it from within the program, without the help of the additional .gif files

The actual way i am using the image is

image = PIL.Image.open('image.gif')

So it would be helpful if you could be precise about how to replace this code

回答1:

Continuing @eatmeimadanish's thoughts, you can do it manually:

import base64

with open('image.gif', 'rb') as imagefile:
    base64string = base64.b64encode(imagefile.read()).decode('ascii')

print(base64string)  # print base64string to console
# Will look something like:
# iVBORw0KGgoAAAANS  ...  qQMAAAAASUVORK5CYII=

# or save it to a file
with open('testfile.txt', 'w') as outputfile:
    outputfile.write(base64string)


# Then make a simple test program:

from tkinter import *
root = Tk()

# Paste the ascii representation into the program
photo = 'iVBORw0KGgoAAAANS ... qQMAAAAASUVORK5CYII='

img = PhotoImage(data=photo)
label = Label(root, image=img).pack()

This is with tkinter PhotoImage though, but I'm sure you can figure out how to make it work with PIL.

Here is how you can open it using PIL. You need a bytes representation of it, then PIL can open a file like object of it.

import base64
from PIL import Image
import io

with open("picture.png", "rb") as file:
    img = base64.b64encode(file.read())

img = Image.open(io.BytesIO(img))
img.show()
